I used to use C&C exclusively, but I'm phasing out what I have left of it. I discovered after using a spool of Gutterman that the C&C creates a whole lot of lint, and the problems I sometimes have are a result of it. I have some connecting threads thread, that I haven't tried yet. I haven't been quilting very long, so I'm still trying things out, but I know I'm done with coats and clark.
